To all whom it may concern: 1 I

Be it known that I, E WARD H11 'Wnnnnn, acitizen of the United States, 'anda resident of Chicago, in the county ofCook and State of Illinois, have invented certain new. and useful Improvements in Train-Control Apparatus, of which the following, reference being had to the drawings accompanying and forming apart'hereof, isa specification. U This invention relates to that class of train signal apparatus by means of which signals are displayed in the cab or engine of a railway train, or in a motor ofelectrically propelled trains, and the'person in dition of the track upon'which the trainis about. to travel.

Among the objects of this-invention is to obtain an apparatus which isautomatic inaction; which. wlll display signals indieating that the track is clear or occupied,

as the conditions exist; and to obtain anapparatus which, will automatically apply brakes to stop the train, incase of t being dangerous to proceed. Additional objects are to obtain an apparatus of the kind named which is certain in operation; economically made and installed, and not liable to get out of order. Additional objects are set forth in the specification and lllnstrated in the drawings.

' Assuming, with the hereinbefore recited installations made, that a train approaches a crossing from north or south, tl1e t'ollovving circuit, called by me the free circuit.

as it indicates by the signals given that the crossing is free, is closed, When brush M comes in contact with special rail K. From battery F on the right hand side of Fig. 1, on conductor 9 to the coils E, E, of relays A, A, on conductor 9, Which is branched from the coils of electromagnets E, E, to standard D of relay A to contact point d of said relay A, on conductor 13 to pivotal point a on standard a, conductor 9 to and through fuse Z, on conductor J to special rail K, conductor I: to special rail K on the opposite side of the crossing to brush M, conductor m (see Fig. 2) to and through fuse u and to lamps N and 0, there dividing: through. lamps N and again on conductor m to standard p and contact point p of relay P, on movable conductor 39 to and on conductor m to terminal M, and Wheel Z to the rail and ground; thence to ground X and on conductor G back to said battery F. From the point of division of said circuit the elements are, lamps O, conductor m from said lamps to coil 12 of relay P, conductor m to and through coil 1?, P to terminal IV, and from thence as above traced. By the closing of the above circuits the movable conductors B, B, of relays A A. are pulled down, being armatures to coils E, E, and said coils being energized, thereby interrupting a correllO of relay a circuitis clOsed Which, startingfromv batadjusted sponding circuit of the east and west tracks which is hereinafter traced,:.at :contactpoint ld, of. said relayA, The .movable conductor B" of relay A is turned on its pivotal point a thereby moving. it from con- 7 tact pointclwto contactpoint (Z, and 010s "ing a circuit through the traclrside installa- .A 'tion' for lamps 1.

It will be observed that the current passing from battery-F through the lamps 0,0, and coils n", n of relays 1 ,21 is not suflicient to so energizesaid coils as to pull down the movable levers 22, 29, and so break the free line circuit "for north and south bound trains, springs P", P being so as to be sufiiciently strong to maintain said movable-levers inthe position indicated by full lines, as against said energizing-of coils a", n".
